1) The rechargeable battery
runtime is dependent, among other
things, on the distance and obstacles
between the receiver and transmit-
ter (condition of the transmission
path) and the age and condition of
the rechargeable battery. After 300
or more charging cycles, the battery
has a capacity of 80 % of the
initial capacity.
Definition of charge cycle:
During a charge cycle the entire
battery power is used, however,
this does not have to occur in a
single charging operation. For
example, you can use a device for
several hours on a particular day,
use approximately half the capacity,
and then fully charge it again. If
the same procedure is repeated on
the following day, this is equal to
just one charging cycle and not two
charging cycles. It can therefore take
a few days for a charge cycle to be
fully completed.
2) If the custo watch is to be
stored for a longer period of time,
it should be recharged regularly
(our recommendation: every 3
months to approx. 60 %)
